All Flashcards
Why is prevention key in managing invasive species?
It's the most effective and cost-efficient way to deal with invasive species.
Explain the importance of monitoring and early detection.
Allows for rapid response, preventing widespread establishment of invasive species.
Why is public education important in invasive species management?
Raises awareness and encourages public participation in prevention and control efforts.
What are the ecological impacts of invasive species?
Outcompete native species, alter ecosystem processes, reduce biodiversity, and change food webs.
Why are invasive species a major threat?
They can cause significant ecological and economic damage.
Why is it important to consider the pros and cons of control methods?
To minimize the potential negative impacts on the ecosystem and human health.
Explain the concept of competition in the context of invasive species.
Invasive species outcompete native species for resources like food, habitat, and sunlight, leading to decline in native populations.
What role does transportation play in the spread of invasive species?
Human activities like transportation, trade, and travel are major pathways for invasive species to spread to new environments.
Why is biodiversity important when considering invasive species?
High biodiversity can make an ecosystem more resistant to invasion, while low biodiversity can make it more vulnerable.
What is the significance of 'non-target species' in chemical control?
Chemical control can unintentionally harm non-target species, disrupting the ecosystem.
What are the steps for preventing invasive species introduction?
Quarantine and inspection of imported goods, control of pathways, and public education.
Outline the process of Integrated Pest Management.
Identify the pest, monitor the population, determine action thresholds, implement control tactics, and evaluate effectiveness.
What are the steps involved in biological control?
Research potential agents, test for host specificity, introduce the agent, and monitor its impact.
Define invasive species.
Non-native species that cause harm to the environment, economy, or human health.
What is Integrated Pest Management (IPM)?
Using a combination of different control methods for effective and sustainable results.
Define 'Early Detection and Rapid Response' (EDRR).
Taking action as soon as new invasive species are detected.
What is biological control?
Introducing natural predators, pathogens, or competitors to control invasive species.
Define habitat modification.
Altering the environment to favor native species and make it less suitable for invasive species.
What is chemical control?
Using pesticides or other chemicals to kill or inhibit the growth of invasive species.
Define physical removal.
Manually removing invasive species individuals or populations.
What is a non-native species?
A species living outside its native distributional range, which has arrived there by human activity, either deliberate or accidental.
Define quarantine.
Isolation to prevent the spread of something considered dangerous, like invasive species.
What are control measures?
Methods used to manage or eradicate invasive species once they have been introduced.
